1 Claim.

The invention relates to closure devices, or clamping rings, forsecuring covers or lids on containers. One of the main objects of theinvention is to provide a closure device which may be adapted to a greatvariety of containers and which can easily be clamped on such containersand as easily removed therefrom.

Another object is to provide a closure device which may be efiectivelylocked so as to prevent it from being dislodged in shipping or handlingthe containers. A further object is to provide a closure device ofsimple construction consisting of few parts, which are not readilybroken or apt to get out of order, which occupies but small space on thecontainer, and which can be manufactured and assembled with thecontainer at low cost.

These and various other objects and advantages will be readilyunderstood from the following description and from the accompanyingdrawing of preferred embodiments of the invention in which, however,modifications may be made without departing from the scope of theappended claim. In the drawing:

Fig. l is a fragmental, top view showing the closure device applied to ametal drum;

Fig. 2 is a fragmental side view of Fig. 1 shown partly incross-section;

Fig. 3 is a similar side View, but shown with the clamping ring slightlymodified;

Fig. 4 is a fragmental, side view of a certain detail of theconstruction;

Fig. 5 is a fragmental, side elevation of another container shown with asomewhat modified clamping ring;

Fig. 6 is a fragmental, side view of the ends of the clamping ring shownin Fig. 5;

Fig. 7 is a cross-sectional side view of the clamping ring, taken on theline l'! in Fig. 5;

Fig. 8 is a rear view of the clamping plate shown in Figs. 1, 2 and 3;

Fig. 9 is a detail view of the wedge shown in Figs. 5 and 10; and

Fig. 10 is a fragmental, side elevationof still another container shownwith still another modification of the clamping ring.

Referring first to Figs. 1,2, 4 and 8, the upper part of a container, asfor example a metal drum is shown at H3 and the cover at H. The cover isprovided with a flange l2 which extends outwardly and downwardly overthe top of the container. The closure device consists of a ring I3,which in this instance is corrugated similarly to the corrugations onthe container so as to fit in the upper corrugations, as plainly shown.

10 It is evident that, when this plate is forced down over the lips l4and Hi, the band will be drawn tightly around the container and thusclamp the cover securely in place. So that the clamping plate may not bedislodged in. shipping 15 or handling, I preferably out two slots 19 and2!] in the sides of the plate so as to form two tongues 2i and 22. If,after the plate has been tightly wedged on the band, these tongues arebent in underneath the lips l4 and I5, it is evi- 2o dent that the platecannot be dislodged or removed, except by straightening out thesetongues.

Fig. 3 shows a similar container 23, but in this instance the band 24,instead of being corrugated as in the former case, has merely its lower25 edge 25 bent into the second corrugation of the container. All theother parts are similar to the parts just described and have thereforebeen similarly numbered.

In Fig. 5, the container 26 is provided with an 30 undercut neck 21. Inthis case the band 28 is provided with an upper flange 29, which fitsover the cover 30, and. with a lower flange 3|, which fits under theshouldered neck. The ends of the band, as plainly shown in Figs. 5, 6and '7, are 35 made to overlap each other. One end of the band isprovided with an outwardly embossed portion 32 in which a similar, butsmaller, outwardly embossed portion 33, formed on the other end of theband, is nested. Slots 34, 35, 36 and 40 31 are formed in the upper andlower edges of the embossed part and each set of these slots, as plainlyshown, are tapered.

With this form of a band an ordinary wedge 38, such as shown in Figs. 5,7 and 9, is employed. The ends of the band are overlapped and the wedgeis driven through the slots, thus clamping the band tightly around thecontainer and clamping the cover in place. In this instance a gasket 39has been shown between the cover and the top of the container, and it isevident that such gaskets might also be used with the other embodimentsshown.

To prevent the wedge from being dislodged,

a plurality of perforations 40 are formed in its lower end and a tongue4i is formed dependently from the embossed part 32. If, after the wedgeis in place, this tongue is driven into any one of the perforations, itis evident that the Wedge cannot be dislodged.

In the embodiment shown in Fig. 10, a somewhat different container 42 isshown. The cover 43 is held in place by the band 44, which is shaped asplainly shown. Its lower edge 45 extending into one of the rectangularcorrugations 46 in the container. The ends of this band are similarlyconstructed as the ends of the bands just described and a Wedge of thesame construction is employed.

While I have shown and described the closure device as employed withcontainers made of metal, it is evident that this device may as readilybe employed with containers of other types, and I therefore do not Wishto limit the invention to any particular kind, size or shape ofcont'ainer.

Having described the. invention and its ob-- jects, what I claim as newand wish to protect by Letters Patent is:

A device for clamping and fastening covers on containers having anundercut neck, comprising an open ring formed of a band and having anupper annular flange extending over the edge of the cover and a lower.annular flange extending in under the neck; the ends of the bandoverlappingeach other and shaped so that one end may nest in the other;tapering slots formed through the upper and lower flanges of said nestedparts; a wedge insertable in said slots for tightening the ring when thewedge is driven in place; and means for locking the wedge to the ring,comprising a vertical series of horizontal slots in the wedge and atongue on one of the overlapping parts for engaging said. slots.
